From Few to Many Emitters Cavity QED: Energy Levels and Emission Spectra From Weak to Deep-Strong Coupling
Andrea Zappalá, Alberto Mercurio, Daniele Lamberto +3
We present a systematic study of the properties of systems composed of two-level quantum emitters coupled to a single cavity mode, for light-matter interaction strengths rangin…
Renormalization and Low-Energy Effective Models in Cavity and Circuit QED
Daniele Lamberto, Alberto Mercurio, Omar Di Stefano +2
The quantum Rabi model (QRM) is a cornerstone in the study of light-matter interactions within cavity and circuit quantum electrodynamics (QED). It effectively captures the dynamic…
Circuit QED Spectra in the Ultrastrong Coupling Regime: How They Differ from Cavity QED
Samuel Napoli, Alberto Mercurio, Daniele Lamberto +3
Cavity quantum electrodynamics (QED) studies the interaction between resonator-confined radiation and natural atoms or other formally equivalent quantum excitations, under conditio…
TRK Sum Rule for Interacting Photons
Salvatore Savasta, Omar Di Stefano, Franco Nori
The Thomas-Reiche-Kuhn sum rule is a fundamental consequence of the position-momentum commutation relation for an atomic electron and it provides an important constraint on the tra…
Conversion of Mechanical Noise into Correlated Photon Pairs: Dynamical Casimir effect from an incoherent mechanical drive
Alessio Settineri, Vincenzo Macrì, Luigi Garziano +3
We show that the dynamical Casimir effect in an optomechanical system can be achieved under incoherent mechanical pumping. We adopt a fully quantum-mechanical approach for both the…
Scully-Lamb quantum laser model for parity-time-symmetric whispering-gallery microcavities: Gain saturation effects and non-reciprocity
Ievgen I. Arkhipov, Adam Miranowicz, Omar Di Stefano +4
We use a non-Lindbladian master equation of the Scully-Lamb laser model for the analysis of light propagation in a parity-time symmetric photonic system composed of coupled active…
Dissipation and Thermal Noise in Hybrid Quantum Systems in the Ultrastrong Coupling Regime
Alessio Settineri, Vincenzo Macrì, Alessandro Ridolfo +4
The interaction among the components of a hybrid quantum system is often neglected when considering the coupling of these components to an environment. However, if the interaction…
Quantum-classical correspondence of the Dirac matrices: The Dirac Lagrangian as a Total Derivative
S. Savasta, O. Di Stefano, O. M. Marago
The Dirac equation provides a description of spin 1/2 particles, consistent with both the principles of quantum mechanics and of special relativity. Often its presentation to stude…
Classical Origin of the Spin of Relativistic Pointlike Particles and Geometric interpretation of Dirac Solutions
S. Savasta, O. Di Stefano
Spin of elementary particles is the only kinematic degree of freedom not having classical corre- spondence. It arises when seeking for the finite-dimensional representations of the…
